Is it possible to make hair particles avoid each other?
as you need hairs, using emitter type is not a good idea. try to use 2 different particle systems : 1 for the grass, another for the flowers. Use a vertex group at least for one of them to control where your particles will pop.

you can also use translucency in your materials (petals and grass) to make it less visible.

Or edit the flower particle system (less flowers than grass), uncheck the keep root option to be allowed to move the entire hair.


move the hairs with comb brush and place them where you need, or cut where you don't want them, add where you want some
